Thisinvention relates, to furring strips as used in the plastering of-walls, especially the outer walls of stucco houses wherein the 'plaster is carried on wire mesh or the like. In the construction. of such houses it has beencommonpractice to nail wooden strips.

wire mesh beingv usually nailed: to the .fur-' ring strips, or the Wall and the strips When so used the strips haveseveral disadvantages, amongst which are, the weakening of the plaster coating by reducing its thickness at theposition of the strips and'of forming the nucleus of cracks in the plaster which may be caused byany of 'several adverse functioning of thevstrips in relation to the plaster.

The objects of our invention are to pro- Which is easier to'apply than a wooden strip, is lower in cost, which may be bent around arched windows and the like'if desired, and

which will form in combination with the wire mesh stretched over it ,a yielding carrier for the plaster structure very little affected bylthe localized changes inthe supporting wall,thereby preserving to a maximum the original strength of the plaster a coating and insuring its -'freedom from cracks. p r I 7 We carry out our invention by providing a wire fur-ring strlp whlch 1s interlocked by the'plaster to form a reinforced unit with the regular mesh stretched over the furring 7 wire.
